Top 10 Python Language Concepts

This is a self-paced Global Knowledge Digital Learning product. GK Digital learning products are created by worldclass production and instructional design teams to deliver an experience that feels more like a classroom than traditional e-learning with hands-on activities for real-world results. In addition to high quality video content and hands-on labs you will have access to subject matter experts to ask questions for feedback and support.

Entry and mid-level developers are sometimes surprised by the behavior of code. Even more frequently, code is inefficient or doesn't respect the DRY (don't repeat yourself) principle. Topics in this course aim to help the developer understand what's going on “under the hood” and thereby write efficient, reusable code.

Writing efficient code helps to reduce resources consumed while your software is executing and enhances your user’s experience. By making code reusable, your development team can also develop faster.

GK Digital Learning Labs

Implement and call a complex function

Write a custom dictionary class

Create a decorator that encrypts and decrypts a function's arguments and return value

Create mixins to add functionality to a base class

Write a class that tracks temperature in Fahrenheit, Celsius, and Kelvin

Write an iterator that creates a sequence of numbers

Write a random sentence generator

Given a list of records (dicts or objects), print a nicely formatted report

Rewrite this code to use except6ion handling instead of conditionals to catch errors

Rewrite the nonidomatic parts of this code to be more Pythonic

Objectives

What You'll Learn

Leverage the full range of dictionary functionality

Catch runtime errors effectively with exception handling

Develop an appreciation for idiomatic, “Pythonic” code

Target Audience

Mid-level to advanced software developers who have a firm grasp of language fundamentals but want to enhance their understanding of core technology concepts.
